  Impact of Cascade Dams on Flow Variability The presence of cascade dams can significantly influence the multifractal structure of river flow by altering natural discharge variability. Reservoir operations often smooth extreme fluctuations and redistribute water flow across time, which may weaken or modify the inherent multifractal characteristics of the river system. Investigating these impacts provides valuable insights into how human interventions reshape hydrological complexity and affect the long-term stability of river systems. Environmental and Ecological Implications Changes in river flow variability caused by cascade dams can have far-reaching ecological consequences. Altered discharge patterns may affect aquatic habitats, sediment dynamics, and nutrient transport processes. Multifractal analysis helps researchers identify subtle changes in hydrological patterns that could influence ecosystem health and biodiversity. Understanding these relationships is essential for deve...

   Biomass-Based Activated Carbon for Pollutant Adsorption Biomass-derived activated carbon prepared from agricultural wastes such as coconut shells, rice husks, and sawdust has gained attention as a sustainable adsorbent for wastewater treatment. Its high surface area and porous structure enable effective adsorption of dyes, heavy metals, and organic pollutants. Research investigations focus on optimizing biomass activation methods to enhance adsorption capacity and reduce treatment costs. Comparative Performance and Integrated Treatment Approaches Recent research explores the comparative performance of supercritical water oxidation and biomass-based activated carbon in removing textile pollutants. While SCWO is highly effective for complete oxidation of organic contaminants, activated carbon provides efficient adsorption of residual dyes and heavy metals. Integrated treatment systems combining both technologies have shown significant improvements in pollutant removal efficie...
